Based on a true story, Carell is completely transformed for his role as John du Pont, with Channing Tatum and Mark Ruffalo starring alongside the known funnyman as wrestling brothers Mark and Dave Schultz.

The flick tells the tale of how Mark - played by Tatum - is offered a place at du Pont's new training ground, and while the opportunity appears to good to turn down, John's attention comes at a terrible price.

However, it's not all doom and gloom in the new teaser - Channing does go topless at around the one-minute mark!

Sienna Miller and Vanessa Redgrave also appear in the movie, which is due to premiere at the London Film Festival on October 16.
